The last time I discussed these kind of issues with you, I wanted us
to consider allowing the compiler to change it's output default based
upon the output of 'uname'.

This is effectively what Linux distributions on Sparc do, they provide
a special 'gcc' binary that looks at uname's output and munges the
command line to the real 'gcc' as needed.

If the primary users of gcc for this target are going to play these
games anyways, better to provide the facility in the gcc sources
itself.

Anyways, that is a seperate discussion.

Agreed, please install this patch if you haven't already.

Thanks Eric.
